Temperature control with Crayons

Crayons are an alternative way to control temperature when there is a lack of space, or when temperatures rise above 290ºC where strips can't be used.

Temperature control with Crayons

Colour Change Crayon Behaviour

When applied to pre-heated surfaces, if colour change takes place:

(a) within 1-2 seconds, the temperature is within +/- 5ºC of its rating

(b) instantly, the temperature is higher than its rating

(c) after two seconds, the temperature is lower than its rating

Accuracy: +/-5ºC


120   120ºC/248ºF    
245   245ºC/473ºF 335ºC/635ºF 505ºC/941ºF
600   600ºC/1112ºF    


Temperature monitoring in the textile industry

Temperature measuring devices specially designed for their use in textile industries. This temperature control prevents the over-heating which could afterwards cause broken fibers, and also alerts when heating is weak giving place to a fragile union between cloths.

Irreversible TDI Temperature sensor labels HACCP

The TDI irreversible temperature indicator labels are designed to withstand the extreme conditions within an Industrial Dishwasher, allowing equipment cleanliness standards to be monitored during disinfection processes. The TDI asures that the selected temperature in the dishwasher has been achieved, that is indicated with a permanent change in colour. Dishwashers used for catering services usually work within 60 to 66º C, but nowadays, the minimum temperature should be 71ºC which is the reference temperature where the materials are considered to be disinfected.

This thermometer has been specifically designed to withstand the conditions undergone in the washing cycle, including the resistance to the agressive chemical substances applied. All of that without losing its capacity to monitor the temperature correctly. Hobart, known dishwasher manufacturer, collaborated when creating this device. Its final design has a size inferior to the one of a stamp. TDI's secret to succeed is the adhesive material used, which not only stands the whole washing cycle but then is easy to remove by us to attach to the HACCP (Hazard Analysis and Critical Control Point) report.

Thanks to its reliability and easy functioning, TDI guarantees higene responsibles that they are using disinfected dishes.

Micro temperature indicators

Micro-Indicators are temperature sensitive strips with a reduced size which makes them specially useful to record increases in temperature in electronic devices such as condensers, resistances, transistors and many others, to prevent malfunctions. These thermometers are very easy to use: You just have to stick them on the device. When the critical temperature is reached the strip turns black revealing a posible malfunction. As these strips rest on the surface to be monitored they give a precise reading of the exact temperature the device undergoes. Furthermore the strips can be attached to a document as part of a quality control record if required. There are three main types of Micro Indicator which are selected depending on the kind of temperature control required:

Tempasure - Low temperature measuring device

 TempasureTempasure detects exposure to low temperatures, it is irreversible and very precise(+/-2ºC). Its difference with the Chillchecker, is that it changes colour when the temperature goes below the chosen critical point (check for available temperatures). Its design is based on the fact that it has to monitor low temperatures. which could damage irreversibly perishable goods such as pharmaceutical substances, food, medical equipment, photographic liquid… or any other product which could be damaged when frozen. Thanks to the indicator's solid and resistant build, a precise reading is asured at the warehouse as in its transport. Its reduced size - 54,3 mm wide x 17,5 mm high y 5,5 mm deep - and weight 4,25 g, make TEMPASURE smaller than many other products with a similar purpose



1) Let the thermometer adapt to the temperature on the desired surface. Pull the safety flap and stick the termometer on the surface.
2) If the indicator screen remains transparent, it means that the product hasn't undergone critical temperatures.
3) If the indicator screen aquites an intense red/purple color: the equipment or product has undergone critical temperatures.
